I had to leave town for a week and left my buddy in charge of nutes.. He swears it happened overnight? Any help?
We need all the info on your grow including: What type of medium; soil or hydro? What brand and type of soil? Indoors or outdoors? What strain? How old are the plants? What type of lights and how many watts? How far from the lights? What is your watering frequency and source of water? What, how much and when was it fed? NPK? What is the medium/runoff pH and PPM if in hydro? What are the temps and humidity in the room? What size pots? Any bugs? Look real close. Any other pertinent info? If any of these questions have already been answered please disregard as I cut and paste this for everyone. If there is leaf discoloration please TAKE PICTURES WITH ALL GROW LIGHTS OFF, ESPECIALLY HPS & LED's. Taking pictures and taking them with lights off, allows us to see what the leaf discoloration looks like.
Inside standard dwc bucket with hydroton supplemented with co2.. 1000w temps and humidity are fine though we've had a bit of a cold snap .. My buddy didn't record the exact ratio of nutrients he put in so I have no idea though its advanced nutrients ph balanced grow-micro-bloom and runoff is around 2200ppm.. She went into flowering on thanksgiving so she's almost done .. I'll have to wait a few hours for a lights off pic.. Basically every other sugar leaf has yellowed and curled although some colas are completely unaffected ...haven't seen any evidence of insects however a few weeks ago there was a slight mold problem (not on the plant but on debris[dead leaves] on the floor that mixed with a nute spill.. Again out of town and nothing I could do) that I took care of with mild disinfectant after removing debris
Some lights off photos.. Any ideas? I drained her last night filled her up with r/o water for today in hopes to flush .. Sorry about the blurriness but you get the idea
Has RO water been your source water for this grow? If so, did you use a Cal-Mag supplement? BTW: that's a lot of ppm's for run-off.
